Neartheir re'ar ends, saddle ybrackets 141are ser cured :to the beams .12,and these braekets! are hingedly or pivotally engaged upon the lowercrossportions 15of U-shaped hangers 16 which are'fpi'votally mounted at-theirupper Vends in 'lugs or bearing brackets 17` secured tothe .undersideof a rear cross bar 18 of the main frame, .it Vbeingreadilyunderstood that, if'the hangers l16 berocked about ytheir upperends, the beams w12 will be raised or lowered. Extendinglongitudinallylof'the main frame andsecuredlrigidly to 'the' vrear cross.bary 18 vatoppositesides of the fmedial' longitudinal line `of'the'frame are' supporting bars '19 which extend Iunder the archv ofthe'axle 2 and are'providedat their front'ends with eyes or collars 20constituting-bearings fora rocking crankshaft Y21.l j .InvertedEU-shaped braces22 bridge the v vaxle immediately over the bearing bars19v andare secured to Lthe said bars by screws, or other equivalents,l23 so that the bars 19 will be 'firmly supported vand will, in turn,

firmly support the crank shaft 21. As

shown'clearl-y in Fig. 4,1the shaft 21 is inverted `U-shaped and risesabove the axle lof the'machineand the main frame. g To the `-ends ofthev shaft 21 are secured levers vvor `cranks 24 whichv extendyrearwardly over the -:axl'e'and' vhavel their Vrear ends vpivoted tothe :upper endsof links V25 which depend below the main frame and arepivotedfto the beams 12 adjacent kand in rear of the saddle brackets 14,as shown 'most clearly -in Fig. k3.v Loosely mounted vupon the uppershoulder portion of the inverted U-shapedl `:rock shaft21-is a keeper 26which is lheld against `movement endwise of the shaft lby stop collars27 in-anobvious manner. This vkeeper is essentially an arcuateplatespanningand having its central rportion* disposed lbelowa'fpullin'g bar v28. This bar comprises a front vmember 29 having itsfrontend 80- rturne'd down `so as to vpivotally 'engage through aneye'31* at the rear end Aof `the ltongue 7, vand arear pulling member -32which 'passes below the Vshoulder of the shaft 21 and has its vrear'extremity doubled yupon,

itself Asofthatits lend overlies the lsaid shaft,

f member. When the machine is in use, the

thereby set to accommodate machines of different lengths. Thisadjustment also enables the user of the device to accurately adjust thepulling bar so that the lifting of the soil-treating elements will beaccomplished ,in the desired manner. The front end of the pulling barmember 32 is formed into a hook or eye 35 which engages over the frontmember 29 and thereby prevents the member 32 dropping from the frontkeeper 26 fits against the under surface of the member 32, as shown inFig. 2, and it is held in this position by a latch 36 carried by thesaid bar member 32 and having its rear end arranged to engage under thekeeper 26 whereby the keeper will be held tothe said member. The pivotbolt 37 upon which the latch is mounted passes upwardly therefromthrough the bar 32 and is held against loss by a nut 38 on its upperend, a spring 39 being coiled around the bolt between the bar and theVnut so as to permit the latch to be easily manipulated and -atfthe sametime maintain such frictional engagement between the same and an opposedsurface that it will. be held against accidental release. A lspacer 40is preferably fitted upon the bolt 37 between the bar 32 and the latchso that the end of the latch may engage under the keeper withoutexcessive binding against the same or beingapt to be bent or broken.

When the machine is to be drawn over a road or it is desired to maintainthe soiltreating elements out of the ground,'the

latch 36 is moved to one side so that the keeper 26 may swingdownwardly, as shown in Fig. 3,` and a hookv41, carried by the centrallongitudinal bar 42 of the frame, is then engaged in the keeper so thatthe shaft 21 will be held in a forwardly rocked position and thesoil-treatingelements will be maintained in the elevated positionillustrated in Fig. 3. vIt will be understood that, when the shaft 21 isrocked forwardly, the cranks 24 are swung upwardly and, consequently,`alifting force is exerted upon the beams 12 through the links 25.

It is thought the operation of the mechanismv to automatically -lift theblades yor shares from thev soil when a corner of a field, for instance,has been reached will be readily understood from what has been said.With the parts in the normal positions and the machine travelingstraight ahead, the pulling bar will 'be alined longitudinally with the'-tongue 7, and, consequently,

tion shown in Fig. 3 and by dotted lines in' Fig. 2, so that the beams12 and the elements carried by them will be lifted. The `parts will, ofcourse, automatically return to the initial position when the tongueresumes its straight ahead position. l/Vhen the parts are arranged asshown in Fig. 3. so as to posi-V tively suspend the beamsv 12 in anelevated position, the shaft 21 moves forwardly in the doubledorhook-like terminal 43 of the pulling bar and is held by the hook 41 sothat the bar then exerts no influence upon the shaft, even when swung toone side.

Then the machine isto be drawn by a tractor, the draft device 4 and the'front steering wheels, together with the ,tongue 7, are removed and thedevice shown in Figs. 5 and 6 is substituted therefor. In this device,there is employed a. coupling 44 con-v which is adapted-torest upon thedrawbar.

bolt or pin 48 being inserted through an opening 49A provided in thebridge piece 45 and in asimilar opening in-tlie drawbar 46 of thetractor. A draft kbar 5() is disposed *be-V over the draftbar V50 `is`a-setting bar 54 a;

which -is provided at its rear endwithuan eye 55 receiving thedownturned end of the pulling bar 'member 29, and the opposed` 46 ofthetractor, indicated at.47,a coupling edges of the bars 50 and 54 areconstructed 56 carried by the coupling-44- between the hand lever 57which is fixed` to the axle or with racks 55 with which meshes a pinionshaft ofthe pinion. A locking plater58 is secured to one side of thecoupling 44 andfis engaged by a latch 59 mounted upon the lever 57 sothat the parts will be held in any set posit-ion. 54 inl the properrelation and prevent separation lof the same, while permitting relativelongitudinal relative .movement thereof,

guiding barsor yokes 60 are each secured to To maintainy the bars 50 andone of the bars to project past the other bar,

as shown in Fig. 5, rollers 61- being provided Y at the ends of theguiding bars so as to hold the the bars 50 and 54 toward each other andinY mesh with the pinion 56. By properly set-k ting the lever, the draftbar and the setting bar 54 will be caused to move longitudinallyrelative to each other andthe pull ing bar Q8 will thereby be set'soa'sto exert the proper pull upon the shaft 2l and also set the blades orother soil-treating' elements to run at the desired depth in the ground.

lith this tractor coupling attachment, f

bar andthe eye 55 will, consequently, be

swung` laterally so that a pull will be exerted upon the rock shaft 2lthrough the bar 28 in the same manner as in the first describedembodiment of the invention. It will be noted upon reference to Fig. 5that the lever 57 may be easily manipulated from the tractor seat.

When a machine is equipped with my invention, the operator may devotehis entire attention to handling his draft team or operating the tractorinasmuch as it willnot be necessary for him to adjust the blades orshares in the slightest degree when turning a corner or reversing histravel after reaching the side of a iield. By elongating the pullingbar, the soil-treating elements `will be set to run at a lower depththan would be the case if the bar be short, and by reason of this factsaid elements can be easily set to run at any desired depth. Should thesaid elements choke for any reason the driver of the machine may easilyreach down from the seat and lift the beams manuallyV so as to clear theobstruction or remove the clicking accumulation. To meet this emergencywhich sometimes, but not often, occurs, a hooked bar maybe providedwhichwill be carried loose upon the m'achine and which the driver may easilyextend downwardly to engage under the beams 12 so as Having thusdescribed they invention, I
